My iPhone 4 external speaker does not work. It is NOT in headphone mode, all though the headphones work fine. My phone will not ring or play music, etc, but will occasionally ring for a second or two when I'm getting a call. I'll use my volume buttons to try and see if the speaker will work, and a volume bar won't even show up under the ringer icon.
iPhone 4, iOS 7.0.6
This is charging port fault. Clean iPhone charging port very well with toothbrush and small amount of isopropyl alcohol. If still problem, replacement part is iPhone charging port with flex cable, lower mic, and home button flex connector, all a single part. Apple handles this problem with replacment iPhone 4 for $149, make Genius reservation to avoid long wait time at Apple Store.
The same happemts with my 4S
